2.2 DESCRIPTION  
Figure 1. Typical Model IM1/I application  
The Patton IM1/I QuikConnect™ Ethernet WAN bridge module  
installs in Patton’s copper and fiber base units to provide seamless  
Ethernet LAN extension. The Patton IM1/I performs the bridging  
function between two physically separate Ethernet LANs at the MAC  
level. Operation of the Patton IM1/I is transparent to higher network  
level protocols such as TCP/IP, DECnet, NETBIOS and IPX.  
Once installed in the local Patton base unit, the Patton IM1/I works  
in a “plug and play” manner to forward LAN broadcasts, multicasts and  
frames destined for the peered Ethernet LAN at the remote end (the  
Patton base unit at the remote end must also be equipped with an IM1/I  
module). Using the Patton IM1/I, peered Ethernet LANs can be linked  
over leased 2-wire/4-wire, DDS, PCM and campus fiber circuits.

3.0 CONFIGURATION  
4.0 INSTALLATION  
The Model IM1/I is completely plug and play. This section tells you  
how to make the connections.  
The Model IM1/I module plugs into Patton’s fiber and copper  
baseband modems to provide Ethernet LAN extension. The IM1/I has  
no switches or jumpers and does not need to be configured. However,  
factors such as ty type of medium, throughput across the link and  
clocking mode must be determined by the settings of the baseband  
modems. Please refer to your baseband modem (i.e. 1092A, 1093,  
1095, 1185, etc) to make the following settings.  
4.1 INSTALLING THE QUICKCONNECT™ MODULE  
Each Quick Connect Module™ has a 50-pin card edge connector  
on one side and an ethernet interface on the other. The instructions  
below describe how to remove the existing QuickConnect™ Module  
and how to install the new IM1/I module. If your base unit does not  
have an existing QuickConnect™ already installed, please skip to  
section 3.2.2.  
1) Bit Rate: The DTE rate setting of your base unit corresponds  
to the throughput of your IM1/I bridge module. Use higher  
speeds to allow maximum throughput to your extended LAN.  
4.1.1 Removing the Existing QuickConnect™ Module  
NOTE: The IM1/I only supports synchronous speeds.  
1) Turn the power switch off. Leave the power cord plugged into a  
grounded outlet to keep the unit grounded.  
2) Clocking Mode: Set the clocking modes on the base units so  
that one unit is configured for Internal clocking mode and the  
other unit is set for Receive Recover clocking mode.  
2) Loosen the two thumbscrews on the module by turning them  
counterclockwise.  
3) Grasp the two thumbscrews and gently pull the module from the  
unit. Apply equal force to the thumbscrews to keep the module  
straight during the removal process  
BASE UNIT CLOCK MODES

Unit “B”  
Internal Clock Setting  
Receive Recover Clock Setting  
NOTE: Unit “A” and Unit “B” are arbitrarily chosen. It does not matter which  
unit is “A”, and which is “B”.  
3) All other base unit settings depend upon your application and  
on the application medium (twisted pair or coaxial cable)

3.1.2 Installing the New QuickConnect™ Module  
4.2 CONNECTING TO THE 10BASE-T ETHERNET PORT  
1) Make sure the power switch on the base unit is off. Leave the  
power cord plugged into a grounded outlet to keep the unit  
grounded.  
The RJ-45 Ethernet port on Model IM1/I is designed to connect  
directly to a 10BaseT network. Figure 3, below, shows the 10BaseT  
RJ-45 port pin description. You may make connections up to 330 feet  
using Type 4 or 5 cable.  
2) Hold the module with the faceplate toward you and align the  
module with the guide slots in the rear panel of the base unit.

2 TD- (data output from IM1/I)  
3 RD+ (data input to IM1/I)  
4 (no connection)  
5 (no connection)  
6 RD- (data input to IM1/I)  
7 (no connection)  
3) While keeping the module’s faceplate parallel with the base unit  
rear panel, slide the module straight in–so that the card edge  
contacts line up with the socket inside the chassis. Figure 2  
(below) shows how a Quick Connect Module plugs into the rear  
of the base unit.

4.2.1 Connecting the 10Base-T Ethernet Port to a Hub  
e  
The Model IM1/I 10Base-T interface is configured as DTE (Data  
Terminal Equipment), just like a 10Base-T network interface card in a  
PC. Therefore, it “expects” to connect to a 10Base-T Hub using a  
straight-through RJ-45 cable. Use the diagram below to construct a  
cable to connect the IM1/I to a 10Base-T Hub.

NOTE: The card edge connector should meet the socket when  
it is almost all the way into the chassis. If you encounter a lot of  
resistance, remove the module and repeat steps 2 & 3.  
4.2.2 Connecting the 10Base-T Ethernet Port to a PC (DTE)  
4) With the card edge contacts aligned with the socket, firmly seat  
the module by using your thumbs to apply pressure directly to  
the right and left edges of the module faceplate. Applying  
moderate and even pressure should be sufficient to seat the  
module. You should hear it “click” into place.  
The Model IM1/I 10Base-T interface is configured as DTE (Data  
Terminal Equipment). If you wish to connect the IM1/I to another DTE  
device such as a 10Base-T network interface card in a PC, you must  
construct a 10Base-T crossover cable as shown in the diagram below.

5.0 OPERATION  
4.3 CONNECTION TO THE LINE INTERFACE MEDIA  
Once the Model IM1/1 is installed, it should operate transparently.  
This sections describes power-up, general operating instructions, and  
the LED status monitors.  
Instructions for connecting the line interface media (twisted pair , or  
fiber optic cable) are contained within the base unit user manual.  
Please refer to the base unit manual for connection details.  
5.1 OPERATING INSTRUCTIONS  
Notice! Any terminal cable connected to the Model IM1/I  
must be shielded cable, and the outer shield must be 360  
degree bonded–at both ends–to a metal or metalized backshell.  
In order to operate, the Model IM1/I must be installed in the base  
unit. It also requires a 10Base-T connection. After power is applied,  
the IM1/I automatically starts performing the bridging function without  
further user intervention. MAC addresses discovered are automatically  
loaded into the MAC address table. They are automatically deleted  
from the MAC address table if they experience an inactivity of 8  
minutes.  
4.4 CONNECTING TO AC OR DC POWER  
Instructions for connecting the power supply Universal Interface  
AC Power Supply and DC Power Supply option) are contained within  
the base unit user manual. Please refer to the base unit manual for  
connection details.  
5.2 POWER-UP  
Before applying power to the IM1/I, please be sure it is properly  
installed in the base unit. Then make sure that unit is connected to the  
appropriate power source (Universal Interface AC Power Supply or  
DC Power Supply). Then power-up the base unit using the rear power  
switch .  
WARNING! The Model IM1/I interface card has been  
specifically designed to work with UI and DC versions of  
Patton Electronics base units. Use with 120/230VAC  
versions could result in damage to the unit. If you are  
unsure of your base unit power supply, please contact  
Patton Electronics technical support at (301)975-1000 or at

1 pulse = system status is okay  
2 pulses = no MAC entries in the MAC Address Table  
3 pulses = Clear to Send (CTS) or Carrier Detect  
(DCD) from base unit are not asserted  
4 pulses = IM1/I buffer is saturated  
5 pulses = WAN receive frame(s) too large  
6 pulses = WAN receive frame(s) not octet aligned  
7 pulses = WAN receive frame(s) aborted  
8 pulses = Detected WAN receive frame(s) with CRC  
9 pulses = Detected LAN receive frame(s) too large  
10 pulses = Detected LAN receive frame(s) not octet
